Yellow spots over paintwork

19 posts in this topic

Both our cars seem to be covered in yellow spot like mustard splatter within days of being cleaned at the moment. Google seems to suggest everything from small bird poo, pollen or bee poo. I presume it pollen but doesn't come off very easily especially if its been on the car in the sun for a few days. Its seems to almost ping off with you nail. I washed the car tonight and when leathering off noticed about 20 or so over multiple panels. They come off if given a good buff with the leather but don't want to mark the paint. Any tips of best easy removal and WTF they are.

I have heard of similar before on white cars parked close to railways. In that case it was iron filings and removal was facilitated with Iron-X or similar.

Are there any chemical plants or industrial chimneys pumping sh!t into the atmosphere close by?

We have exactly the same on our cars at the moment!

Seems to happen overnight only.

Very odd.

I'm sure the dust is getting worse and worse over the years.  Yes those kind of marks look familiar.  Autoglym Super Resin Polish is quite a straight forward product to rid anything like that which is 'bonded on'

 

Spent hours with a bottle of Dodojuice cleanser last Saturday trying to get the paint of the S4 smooth to the touch.  Didn't wash the glass, wheels or exhaust - simply washed the body and spent hours on the paint.  Body still feels rough to me but I was too knackered to give it a second layer.  Probably give it a layer of Autoglym Super Resin Polish to try and rid all the contaminants on the paintwork, followed by a layer of carnauba wax

That's quite common in the US and mainland Europe where new cars are delivered by train, doubt it's thats in this case. 

 

I guess it's pollen, pollen is quite sticky and I presume when it comes into contact with hot bodywork 'cooks' itself onto the paint. A good wash should shift it.

Both my cars are covered with SRP, the JCW also has 3 layers of HD Wax but after a month it's lost that slick feeling. I need to use HD Cleanser on the RR, then reapply SRP and finally waxing it - not looking forward to that weekend  :unsure:

Three full layers - feck that!  Sounds like your paint is in fairly good condition to start with at least!

It's 9 years old, now looks brand new  :grin:  HD Wax goes on, and comes so very easily +++

Looks like pollen to me, damage from parking near railways doesn't look like that, we used to park our fleet vehicles on a piece of land next to the railway line and they got the marks on the paint from iron filings, but they didn't look like that.

I've noticed similar marks on all our cars, i'm sure it's pollen from our neighbours garden.

Could it be juice / resin from tree sap, have you loads of trees in the area. Even if the cars aren't directly under tree wind and breeze could transport the resin a distance.

Try checking neighbours cars to see if the problem is common to all or just isolated to your cars.

Digested and excreted (by bees) pollen. Get it all the time here.

Park your car away from the bee flight path (hive to flowers etc) and the spots will magically disappear...

...till the bees change their route.

Carnuba wax finish on your cars makes removing the spots a heck of a lot easier. Though "pinging" them off the paint when it has baked in 40C+ temps for hours is indeed a small bit of puerile fun. :)

What you've done there is put HD cleanse on, and then remove it with SRP. Ideally you would pick one or the other. They won't layer.

Rachel is spot on. Used to come across this when I was detailing, and it was always with clients who had lots of flowers lining their driveway. A mild clay such as sonos is the best way to remove it without damaging your paint. Obviously though this also removes any protective layers you have on such as wax etc. mind you, rubbing your paint with leather will do a similar thing.
